ATC fee for providing separation for each aircraft should definitely be
charged to each aircraft... The charge should be some tiny percentage of the
gross revenue earned on that flight ... Lets pick a multiplier, say 0.001..

Assume 300 passengers paying an average $300 ticket = $90,000 for KORD to
KDFT... times 0.001 = $90 that ABC Airlines sends to the feds... (actually
it is easier than that... Quarterly, ABC Airline sends 0.001 of it's gross
revenue and you don't have to fool with tracking routes)

Now, Joe Schmuk flying his Whizbanger Four flies the same route... Gross
revenue for the flight = $0.00... times 0.001.. Charge = $0.00

Seems fair to me...

" It costs the same
to separate a 747 from a 172 as it does to separate the 172 from the 747.
Obviously the 747 is paying a lot more for the service than the 172. The
airlines want to change this and the 172 owner (and Gulfstream owner)
wants
to keep it the same as it is now.
